Explains how substantial energy savings can be achieved by integrating the distillation system into the slop concentrating evaporator of a fermentation plant. Presents diagram of a fully integrated system. Advantages of a combined system include considerable improvement in the energy balance of a fuel alcohol plant; concentration of alcohol in the feed becomes much less important; improvement in the recovery of alcohol in the feed; and it enables simpler stripping of alcohol from the fermented liquor. Such systems will reduce the net extra heat required for distillation from one-half to one-third that normally needed. The energy required for slop evaporation is slightly less than normally needed by a highly efficient vapor compression evaporator operating alone.
